For a healthy mind and an active body, B-1 is one vitamin you can't be without! The first B-vitamin to be discovered, thiamin plays crucial roles in energy metabolism and nerve cell function, making it essential for the health of both mind and body. Because thiamin can't be stored in the body, it's important to get a good supply every day. Our Vitamin B-1 capsules are a convenient way to ensure that you meet your daily needs.

Rated 1 out of 5 by thebecca Water soluble B 1
Regular thiamine (B !) go right through me. I personally get no benefit from them, consequently, they are a poor bargain for me. To rate this product higher they would have to have a money back guarantee.

Rated 5 out of 5 by Nemo222 My prespective
This product is exactly as described. I purchased this product because my B complex complete liquid vitamin was missing B1. With this product I was able to get all of the recommended daily B vitamins. I recommended this product for both quality and price.

My doctor said I was low on B-1 so I just started taking this supplement. I feel like I have more energy since I started taking it.

Rated 5 out of 5 by Paturnia Great product
Great Vitamin B-1 supplement. The capsule is a bit big but very easy to swallow. Will keep buying it, since multivitamin/minerals often do not have enough B-1. Thank you Swanson!

When I have problems with my feet moving just as I begin to fall asleep, I take 100 mg of B1 and I have a good nights sleep.

Rated 5 out of 5 by JEDGE B1- AN AHA
Several years ago I read of B1 used to help reduce embarrasing memory slips and decided to try it. It worked and after while as usual forgot about it until the need arose again as my 80's arrived I immediately thought of Swanson's and am pleased so say its working finely again, thank you so much for continuing carrying all the basics, old as well as new.

Rated 5 out of 5 by Kira Best Value for B1 I have seen
I love this product. It works just as well as more expensive B1 vitamens I have purchased, and is much less expensive and much easier to swallow (I prefer capsules to tablets). I take this product everyday and really notice a difference in my energy level if I forget to take it.
